(Test Method)Standard Test Method for Determination of Neutral Fatty Matter Contained in Fats and Oils
Standard Test Method for Determination of Neutral Fatty Matter Contained in Fats and Oils
SIGNIFICANCE AND USE
3.1 This test method is intended for the determination of the neutral fatty matter contained in fats and oils by means of ether extraction.
SCOPE
1.1 This test method covers all degraded glycerides, since they are neutral fats. However, this procedure does not necessarily determine all the mono and diglycerides that may be present in the sample. This is due to the water soluble characteristics of some mono and diglycerides.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview
ASTM D5560-95(2018) is the internationally recognized Standard Test Method for Determination of Neutral Fatty Matter Contained in Fats and Oils, developed by ASTM International. This standard specifies procedures for quantitatively extracting and measuring neutral fatty matter from fats and oils samples using ether extraction techniques. It ensures consistent, reliable assessment of the neutral fat content-critical for quality evaluation in both industrial and laboratory settings.
This method is well-established in the industry and supports compliance with international trade guidelines as outlined by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
Key Topics
Scope
- Applies to all degraded glycerides, classified as neutral fats.
- May not determine all mono- and diglycerides present, as some are water soluble.
- All measurements are based on SI units.
- Does not address safety protocols-users must follow relevant health and environmental practices.
Test Procedure (Summary)
- Sample is dissolved in alcohol and titrated with sodium hydroxide using phenolphthalein as an indicator.
- Ether extraction separates the neutral fatty matter, which is then isolated, dried, and weighed.
- The calculation provides the total neutral fatty matter content by mass percentage.
Precision and Bias
- Method originates from established protocols by the American Leather Chemists Association.
- Users are urged to verify the reproducibility for their specific use, as original interlaboratory data may not be available.
Referenced Materials
- Utilizes standardized apparatus and reagents, including Erlenmeyer flask, separatory funnel, petroleum ether, and denatured ethyl alcohol.
